Be it known that I, EDWARD W. SMITH, o citizen of the' United States,and niresident of Phledel his, in the countyof Philadel phio. and stateof Pennsylvania, have invented certain new and useful Improvements inStorage-Battery Plates, of whichy the 'ollowin1 is n specification,

The principal ob ect of the present invention is to improe-:e t oconnection of the body of the plate with the sides onrVbottom oi the rimthereof, to the end th'ut the tendency v to fracture anddisintegratiort'st these arts may be successfully opposed, and the'e'ective life of theplote increased.

The invention will be claimed at the end hereof und en' embodiment of itis illustrated in the accompanying drawings in whichf Figures l and 2,are respectively on edge and :i face View of the plate, o portion of thehitter only being shown and the rest being;A

indicated in broken lines, and Fig'.y 3, is e transverse sectional Viewdrown to en en- 4`lorged scale, illustrating features of the in?Ventron.

' Referring to the drawings thebody 1, of the platecomprises n. greatnumber of eje having spaces 3, be tlweenthem, which extend clemthroughthe The body also comprises cross-wise l ronomingreinforcing ribs 4,which nrc spaced some little distance sport.

5, are the sides, 6, is the bottom and 7, is the top of the rim of theplate, which is provided with s. lug 8. ln e plate of the characterdescribed, when in use, there is o tendency on the port of the sides 5,of the rim or frame, to crock, brezil; end subsequently give rise to orupture, that in time ext-ends clear across the plate, thus dividing itin two. This defect ,is present even though the thickness ol these partebe increased, but this defect is avoided in the l manner to bedescribed.

the body end :i out midway of the plate, e

Fig. 3, and indicated upon Fig. 2hy dotted lines inside of' thepletes.This beveled or pointed web really causes the body of the lote to mergegradually into the sides of the lramle so that there is no shor line ofdemarcation between the two, an the effect of it oit-he plate.

Whot I Gleim is: Y

L. A storage battery plete consisting of nv body port of iine ribshaving between them `spaces which extend clear Athrough. the plate and'havingr cross-wise ranging: reinforcin ribs,a'nd ol' n. rim or framethe bottom an sides of which are providedwith e, te ering webthat-extends inward, substantie ly es described.-
